Chapter 1

It's a build to mid or bot with ziggs.
RUNES :you can choose for runes you have 2 goods possibilities.
ITEMS :I use to take a defence item in early game :Abyssal scepter => magic resit ; Rylai => 500hp ; Zhonya => active skill ; Banshee => passive skill, 375hp, 375mana and 50 magic resist.
Will of the Ancients I take that for stay long time in my lane or for regen my health in the jungle to return in the teamfight and if there is an other magus in the team it's good with the aura.
Skill : I use to take a heal or an ignite to stay on the lane or in a teamfight.

This build it's very fun to play and very good.
Use this build and have fun with this Bomber Man. =D
